Used primarily as a corrosion inhibitor in industrial applications, especially in oil and gas production where it protects metal surfaces from acidic environments. Acts as an effective additive in lubricants and metalworking fluids to enhance performance and extend equipment life. Also serves as an intermediate in the synthesis of quaternary ammonium compounds used in biocides and surfactants. Its long hydrocarbon chains provide good solubility in non-polar systems, making it suitable for use in fuel and oil additives to improve stability and reduce degradation.
